# This file is for integration with Google OSS-Fuzz.
# The following ENV variables are available when executing on OSS-fuzz:
#
# /out/ $OUT Directory to store build artifacts (fuzz targets, dictionaries, options files, seed corpus archives).
# /src/ $SRC Directory to checkout source files.
# /work/ $WORK Directory to store intermediate files.
#
# $CC, $CXX, $CCC The C and C++ compiler binaries.
# $CFLAGS, $CXXFLAGS C and C++ compiler flags.
# $LIB_FUZZING_ENGINE C++ compiler argument to link fuzz target against the prebuilt engine library (e.g. libFuzzer).
# This sets the -coverpgk for the coverage report when the corpus is executed through go test
